Micron has announced new memory chips MLC and SLC flash specially designed for professional uses. These have indeed endurance well above current standards. The new chip designed by Micron MLC offers a capacity of 4 GB it is 30 000 cycles of writing, cons 5000 over the previous model. Regarding the SLC, Micron offers a 2 GB chip with an endurance of 300 cycles of 000 entries as against 100 000 in the usual references founder of America. These new chips adopt interface ONFI 2.1 (the output of a chip can achieve 200 MB / s) and are stackable to offer "packages" of MLC 32 GB and 16 GB SLC.

In a video posted on his blog, Micron said that the arrival of these chips is due to the maturity of its burning process to 34 nanometers. The first MLC chips etched into 34 nm and launched late last year had only about 1500 write cycles. They were therefore only used in storage media such as USB sticks and memory cards.

A few months later, Micron could reach 5000 cycles of writing and that is what he considers his MLC "standard". This is significant when one considers that knows the standard for the MLC around 10 000 cycles. The SLC was launched simultaneously with the MLC in turn offers a number of normal cycles, 100 000. A few weeks ago, Micron launched its MLC 3BPC or x3, with 3 bits per cell instead of 2. Both chips announced today that it therefore the logical continuation of this timeline, with a more mature process.

Regarding the competition, there is no information about the endurance of 34 nm solutions from Samsung, and Toshiba 32 nm. The new Micron chips are at the stage of samples, and will not be mass produced until the beginning of 2010.
